A landmark for insulation since 1933
A wide product range
Saint-Gobain ISOVER AB manufacturers glass wool insulation in Sweden. With our products and our knowledge we contribute to energy savings in society. Our head office is in Billesholm in the southern part of Sweden, where we also manufacture glass wool.
Besides glass wool we also sell ULTIMATE insulation and foams manufactured by other companies. We are the only supplier in Sweden to offer a complete range of insulation products with glass wool, ULTIMATE and foams. We use the ISOVER brand for glass wool and ULTIMATE and the STYROFOAM™ and Styrolit brands for foams.
ISOVER in Sweden has a very close cooperation with its sister company in Denmark. The two companies cooperate under the name ISOVER Scandinavia. Thus we can offer more products and higher competence to our customers.
